This invention relates to trouser garments and particularly to a cut-on type of fly front construction for such garments and wherein separable snap fastener elements are employed and set along the full length of a ily front construction such as employed in various types of garments.

The principal object of this invention is to design a fly front construction to accommodate a series of separable snapv fastener elements and particularly to redesign the cuton ily front construction so as to make it more convenient for the wearer in the manipulation of the snap fastener elements for closing up a ily front. This is accomplished by initially cutting one side of a fly front construction with sucient material to permit a double folding yof the material, one fold of two-ply material consisting of a second ily strip to which fastener elements are attached, and this second fly strip folded back upon a portion of the garment considered the under-right ily strip proper and bar tacking it thereto at equal distances between the attached fastener elements, thus providing individual pockets as a part of the under-right y and within which the thumb of the wearers hand may be inserted in the act of snapping the elements together.

Another object in designing this cut-on type of fly front construction is to arranged the material such that in folding it over, the second fold will be positioned away from the extreme edge of the garment to preclude a building up of the garment material along that fly edge.

The invention will be better understood from the detailed description that follows when considered in conjunction with the accompanying drawing showing a certain preferred embodiment of my invention and wherein- Fig. 1 is a front view of a ily construction such as might be employed in trouser garments and showing one part of the front y construction in partially open position.

Fig. 2 is a development layout of the underright fly portion of the garment showing the pattern as it would be before the folding operations.

Fig. 3 is a vertical sectional view taken along the line 3--3 of Fig. 1, but with the i'ly front construction in closed position.

Fig. 4 is a horizontal sectional view taken along the line t-t of Fig. l, but showing the fastener elements in a position about ready to be snapped together.

Fig. 5 is a view similar to Fig. 4, but showing the garment as it would be with the snap fasteners snapped together, and

Fig. 6 is a diagrammatical perspective view showing how the upper en'd of the under-right fly portion of the garment appears when folded.

Referring now in detail to the drawing the numeral I0 designates the right front portion of a trouser garment construction adjacent the y front opening. The numeral II designates the left front portion of the garment construction adjacent the ily portion. The front portions I0 and I I are brought together below the ily front opening by an infolded joining seam I2.

In using the terms "rlght and left to designate certain parts of the garment, I choose to use these terms in the specification as they are conventionally used in connection with the actual garment and not as to the position of the parts as they happen to appear in the patent drawing. It, therefore, should be understood that, when I refer to the under-right ily part of the garment, it will appear at the left of the drawing and the upper left fly part will appear at the right of the drawing.

To provide a cut-on type of fly front construction the pattern followed is more or less in accordance with that shown in Fig. 2. Here specifically the right front portion of the gar-4 ment Ill is extended beyond an imaginary line shown as a dash and double dot line I3 to a fold line indicated by a dot and dash line I4 referred to as the second fold line and which included material will hereinafter be considered the under-right ily strip I5 proper. The lower edge of this under-right y strip I5 is cut on a bias and preferably in the form of an arc I6 that is substantially tangential to the second fold line I4. Extending from the second fold line I4 to another fold line I'I, considered the first fold line, is another strip of included material I8, conveniently termed the mid section, the lower edge of which is likewise cut on an arc I9 comparable to the arc I6. Extending beyond the so called iirst fold line I'I is the remaining portion of the cut-on fly front material designated by the numeral 20, and the lower edge of this fly front portion being likewise cut on an arc 2I somewhat comparable to the arc I9.

Below the under-right fly strip proper I5 the garment is extended as ai; 22 to provide a suiiicient amount of material to the right front portion of the garment to have its end fold and stitched together with the adjacent folded edge of the left garment portion II as at the infolded seam I2 previously mentioned. The upper edge of extended portion 22 -is cut on a bias or an arc 22a having considerable clearance and in a diverging manner relative to the arcuate cut I6 immediately above.

As is the usual custom with all fly front constructions a facing or lining strip 23 is provided to lie back of the under-right fly strip I5. When the extended portion ofthe garment material for the cut-on fly construction is in its extended position as shown in Fig. 2, the outer edge of this lining strip is attached to the outer edge of the end material 2l by a line of stitching 2l extending even through the arcuate portion 2|. two portions lf3 and 2Q are next folded upon themselves along the first fold line I1 to provide a double-ply iiy strip 25 conventionally termed the second ily strip. With the sections I3 and 20 thus folded, a series of fastener elements. preferably studs, are set'along this strip in equally distanced positions. For the next-operation the double-ply second ily strip 2l is folded over against the front of the under-right ny'strip Il along the second fold line Il. It isto be noted that the width of the garment ily portion is somewhatwider than the adjacent mid portion Il. This difference in the width'of the adjacent portions I8 and 20 is purposely designed so as to cause the second fold line Il to be Ldisposed somewhat back from the end or edge portion of the ily strip where the lining is attached thereto as best shown in Figs. 5 and 6. With the fastener elements 26 attached and the second ily strip 25 folded over upon the under-right ily strip II, the former strip is then secured to the underright ily strip I5 at equally spaced intervals as by bar tackings 21. and thus provides a series of pockets 28 (see Fig. 4), the purpose of which will later appear. After the bar tacking operation the outer ends of the garment portion 2li and the lining 23 are folded back upon itself as shown in Figs. 4 and 6 with the lining disposed in back of the under-right ily strip It. 'I'he inner end of this lining is folded back upon itself as at 29 and finally stitched to the garment proper 'as by a line of stitching 30, which line of stitching is more or less in alignment with the seam I2 previously mentioned and as seen in Fig. 1.

Considering now the upper left ily front construction the garment is designed to have a portion overlie the under-right ily strip, which portion is indicated by the numeral 3l. To the underside of this garment portion 3l is secured a under ily strip 32. However, before this under fly strip 32 is secured in` place in order to reinforce it suiciently to take complemental fastener elements for the stud elements 2l on the second ily strip 25, a, reinforcing strip 33 is stitched to the inner face of said ily' strip `32 as by line stitching 34 along the opposite edges thereof, thus providing for a double ply section for the underiiy strip 32. Socket elements 35 .complemental to the stud elements 23 and equally spaced are secured to the double ply portion of the under fly strip 32. The fly strip 32 with the reinforcing portion 33 stitched in place and the elements 3l attached thereto` is next secured to the outer end of the garment ily portion 3| by a line of stitching 36, and the ends folded back. to form an in turned seam 31 in the manner as best shown in Fig. 4 with the under fly strip 32 caused to underlie the garment ily portion 3l. The inner end of the under fly strip 32 is finally secured in place to the left front portion proper Il as by aline of stitching 38.

To finish ofi' the upper part of the garment the usual form of waist band may be secured thereto. As best shown in Fig. 3 the waist band attached to the right front portion I 3 of the garment is of double material thickness Il having its upper end infolded as at 4| and stitched together by a line of stitching I2 in the usual manner. The lower ends of the two ply material of this right waist band 40 are spread apart and each lower edge infolded upon itself as at 43, and compressed against the opposite sides of the garment part Il and at the under-right ily section embracing TheV lli4

elements were A 4 the under-right ily strip il, the lining strip il and the double-fold second ily strip 25, .and all folded parts stitched together as by a line of stitching M. Adjacent the end of this right waist band Il is secured a stud element I5 through both thicknesses ofv the waist band material and in vertical alignment with the stud elements 2l, the element 4I being identical with elements 26.

The left waist band construction 4B is made and attached in a similar manner to the rightwaist band 40, having at its upper edge formed with an infolded seam 41 and stitched at 43. The lower ends of the two ply material of the left baud 4| are likewise spread and infolded as at 43 and stitched as at l0 to the left portion of the garment I i and at the ily portion including the upper left garment portion 3|, the under ily strip 32 and the reinforcing strip 33. After the left waist band 4B is secured in place a socket element BI complemental to the stud element II is secured adjacent the end thereof in vertical alignment with the socket elements 35 previously referred to. I

It is to be noted that all the studs 23 by the manner in which they are attached to the double folded portion 25 are concealed and covered relative to the under side oi' the garment part I0, and itis only-the attaching element of the stud 45 secured to the right waist band It that shows to the under face of the garment. Similarly all the socket elements 3l carried by the upper left i'ly construction are concealed from the front portion of the garment except for the uppermost soci/:et element 5| secured to the left waist band ll, and this will be covered by the belt normally worn with the trousers.

In the closing up of the fly front by reason of the pockets 28 that are provided in the underright ily portion, it will be a relatively simple matter for the wearer to slip ones thumb into the several pockets so as to supportl the underside of the stud members 28 while compressing the front of the upper-right fly portion 3| by the index finger for snapping the series of separable snap fastener elements together in the manner as clearly shown in Fig. 4. By this construction it eliminates the necessity of having to force ones thumb underneath the under-right ily portion as would be required if the fastener attached directly to the y strip II. It is, of course. obvious that minor changes in details of construction and arrangement of parts may be made without departing from the scope of the present invention as set forth in the appended claims.
